I am trying to take a number of dls instruments which have been saved as individual dls files and combine them into a single dls collection. To do so I insert the dls files into a common project and create a new dls collection which will hold all the instruments. After I copy a dls instrument from the inserted collection then paste it into the new dls collection which has at least one other instrument in it, I find that the new copy of the instrument has several of its wave assignments scrambled, usually choosing the waves of one of the other instruments in the target collection. Is there a work around or patch for this problem aside from manually rebuilding each instrument from scratch? Jeff Gatlin Simutronics Corp.
